(vi) SIXTH, any surplus remaining after the irrevocable and unconditional payment in full in cash of all of the Secured Obligations and Obligations entitled to the benefit of such Collateral will be paid to the Borrower or the other applicable Obligors, as the case may be, or its successors or assigns, or as a court of competent jurisdiction may direct.”

	h.	Section 3.4 of the CTA is hereby amended by adding the following as subsection (c):
		If any Priority Lien Secured Party other than the Namoya Purchaser and the RFW Purchaser collects or receives any proceeds in respect of the Priority Stream Obligations or Twangiza Priority Stream Obligations prior to the payment and satisfaction in full of the Priority Stream Obligations and the Twangiza Priority Stream Obligations and a Responsible Officer of such Priority Debt Representative shall have received written notice, or shall have actual knowledge, of the same prior to such Priority Debt Representative’s distribution of such proceeds, whether after the commencement of an Insolvency Proceeding or otherwise, such Priority Lien Secured Party will forthwith deliver the same to the Collateral Agent, for the account of the Namoya Purchaser and/or the RFW Purchaser, as the case may be, in the form received, duly endorsed to the Collateral Agent, for the account of the Namoya Purchaser and/or the RFW Purchaser, as the case may be, to be applied in accordance with clause (a) above.
